Description

Technical Field

[0001] The present invention relates to the technical field of integrated circuit chip packaging and testing, and in particular to a packaging and testing device for integrated circuit chip processing. Background Art

[0002] After wafer manufacturing and dicing, integrated circuit chips need to be packaged and tested to ensure their normal functions and protect the chips from damage by the external environment. The packaging and testing equipment used for integrated circuit chip processing is generally used to test the electrical performance, connection quality and other aspects of the chip after packaging, to ensure the quality and performance of the final product while improving production efficiency.

[0003] A packaging and testing device for integrated circuit chips is disclosed in the patent publication number CN116626475A, which relates to the technical field of integrated circuit chip packaging and testing. Through the cooperation between the supporting box and the first cover and the second cover, it is convenient to perform performance testing operations on the packaged integrated circuit chip under low and high temperature conditions in a sealed space, and can test the sealing effect of the packaged integrated circuit chip under both high and low temperature conditions, and can test the conductive performance of the integrated circuit chip when the temperature changes suddenly, effectively improving the convenience and efficiency of testing the integrated circuit chip at two extreme temperatures.

[0004] The prior art has the following defects:

[0005] Unable to detect the performance of packaged chips under dynamic conditions: Most existing test equipment is designed based on static conditions, mainly detecting the performance of chips under constant current, voltage, and temperature. These devices lack the ability to evaluate chips under complex dynamic conditions and cannot simulate variables in the actual working environment, such as rapid temperature changes or mechanical vibrations. Therefore, it is necessary to conduct comprehensive performance tests under dynamic conditions to discover and solve potential defects and problems in advance, so as to improve the reliability and stability of chip testing.

[0006] Energy waste during environmental simulation testing: Environmental simulation testing plays an important role in verifying the reliability and performance of packaged chips. Existing environmental simulation testing usually has only one environmental simulation chamber, which requires continuous cooling or heating during high and low temperature test cycles, resulting in a lot of energy waste. In addition, the existing environmental simulation chamber cannot apply vibration stress while simulating the environment. Therefore, by setting up two environmental simulation chambers, the test frame can shuttle between the two environmental simulation chambers, and apply vibration stress to reduce the company's operating costs and expand the simulation range.

[0007] Unable to adapt to packaged chips of different specifications: Many test equipment only have fixed fixtures and interfaces, and can only be applied to packaged chips of specific sizes and shapes. Each time you switch to packaged chips of different specifications, you need to readjust or replace the test equipment and fixtures, resulting in a waste of time. Therefore, it is necessary to set up fixtures that can clamp packaged chips of different specifications to improve test efficiency and product quality. Summary of the invention

At this time, the spherical table 423 contacts the limit groove 453 inside the vibration table 451, and the micro-vibrator 452 is started. The packaged chip 443 is driven by the vibration table 451 to be tested in a vibration environment, thereby achieving the effect of improving the reliability and stability of chip testing.

[0061] When an environmental simulation test is required, the mobile base 421 is located at one end of the test bench 41 and placed above the vibration table 451, and the rotating cylinder 31 is started. The lifting threaded rod 32 is driven to rotate in the support frame 2 through the output end, so that the environmental chamber 35 falls down and covers part of the test bench 41 under the drive of the connecting rod 34, and then the temperature and humidity generator 33 is started to apply different temperature and humidity environments in the two environmental chambers 35. The mobile base 421 is moved to both ends above the test bench 41 to make the packaged chip 443 tested in different environments, and when the mobile base 421 is moved out of or into the environmental chamber 35 at one end, the anti-leakage curtain 36 will be opened and closed to prevent the air in the environmental chamber 35 from leaking out, thereby achieving the effect of reducing the operating costs of the enterprise.

[0062] The micro vibrator 452 can be started in the environmental chamber 35 to vibrate the packaged chip 443, or the mobile base 421 can be moved between the two environmental chambers 35 to perform a temperature cycle test on the packaged chip 443, thereby achieving the effect of expanding the simulation range.
